Need a little help with a switch statement

Hi all, I am getting an error in the following script that says 'Operator == cannot be used with a left hand side of type 'System.Type' and a right hand side of type State'. The error occurs at the beginning of the switch statement.

Here is the script:

 import System.Collections.Generic;
 enum State{open, close, inbetween}
 var openSound : AudioClip;
 var closeSound : AudioClip;
 
 var parts : GameObject[];
 var defaultColors : Color[];
 var particleEffect : GameObject;
 var go : GameObject;
 var maxDistance : float;
 var player : GameObject;
 var mytransform : Transform;
 var inUse = false;
 var MyGUI;
 var used = false; //track if the chest has been used or not
 var x : int;
 
 var cnt : int;
 var glow : boolean;
 var state = State;
 
 var loot : List.<Item>;
 var ItemGenerator : ItemGenerator;
 //[RequireComponent(typeof(BoxCollider))]
 //[RequireComponent(typeof(AudioSource))]
 
 //public State state;
 function Start() {
 loot = new List.<Item>();
 mytransform = transform;
 state = Chest.State.close;
 
 particleEffect.active = false;
 
 defaultColors = new Color[parts.Length];
 
 if(parts.Length > 0)
 for(cnt = 0; cnt < defaultColors.Length; cnt++)
 defaultColors[cnt] = parts[cnt].renderer.material.GetColor("_Color");
 }
 
 function Update () {
 if(!inUse)
 return;
 
 if(player == null)
 return;
 
 if(Vector3.Distance(mytransform.position, player.transform.position) > maxDistance && !inUse)
 MyGUI.chest.ForceClose();
 //SendMessageUpwards("CloseChest");
 }
 
 function OnMouseEnter() {
 Debug.Log("Enter");
 HighLight();
 }
 
 function OnMouseExit() {
 HighLight();
 }
 
 function OnMouseUp() {
 go = GameObject.FindGameObjectWithTag("Player");
 if(go == null)
 return;
 
 if(Vector3.Distance(transform.position, go.transform.position) > maxDistance)
 return;
 }
 
 switch (state) {  <<ERROR OCCURS HERE
 case State.open:
     state = Chest.State.inbetween;
     //StartCoroutine("Close");
     ForceClose();
 break;
 
 case State.close:
     if(MyGUI.chest != null) {
     MyGUI.chest.ForceClose();
     }
     state = Chest.State.inbetween;
     StartCoroutine("Open");
 break;
 
 }
 //if(state == Chest.State.close)
 //Open();
 //else
 //Close();
 
 function Open() {
 MyGUI.chest = this;
 player = GameObject.FindGameObjectWithTag("Player");
 inUse = true;
 animation.Play("");
 particleEffect.active = true;
 AudioClip.Play("openSound");
 if(!used)
 PopulateChest();//5
 //yield return new WaitForSeconds(2);
 
 state = Chest.State.open;
 //SendMessageUpwards("PopulateChest", 5); //gameObject
 SendMessageUpwards("DisplayLoot"); //gameObject
 
 }
 
 function PopulateChest() {
 //chest = go;
 for(cnt = 0; cnt < x; cnt++) { //x
 loot.Add(ItemGenerator.CreateItem());
 //loot[cnt].Name = "I:" + Random.Range(0, 100);
 used = true;
 }
 
 }
 
 function Close() {
 player = null;
 inUse = false;
 //SendMessageUpwards.DONT_REQUIRE_LISTENER("PopulateChest", 5);
 
 animation.Play("");
 
 particleEffect.active = false;
 AudioClip.Play("closeSound");
 //yield return new WaitForSeconds(2);
 
 state = Chest.State.close;
 
 if(loot.Count == 0)
 Destroy(gameObject);
 }
 
 function ForceClose() {
 SendMessageUpwards("CloseChest");
 
 StopCoroutine("Open");
 StartCoroutine("Close");
 }
 
 function HighLight() {
 if(glow) {
 if(parts.Length > 0)
 for(cnt = 0; cnt < defaultColors.Length; cnt++)
 parts[cnt].renderer.material.SetColor("_Color", Color.yellow);
 }
 
 else {
 if(parts.Length > 0)
 for(cnt = 0; cnt < defaultColors.Length; cnt++)
 parts[cnt].renderer.material.SetColor("_Color", defaultColors[cnt]);
 }
 }

This is only the second time I have had to use a switch statement and I cannot figure out why its throwing me this error. Can someone take a quick look and see what I'm doing wrong? Thank you!
